List of all binary combinations for a number in Java

Question

I am working on a project involving \"Dynamic Programming\" and am struck on this trivial thing, please help.

Suppose I take 4 as an input, I want to display somethi

Answer 1

here is the code is to find the combination

        //Recursive call of the function to print the binary string combinations
        binaryDigit.printBinary("", 4);
